PATENT GFFICE.

FURNACE WITH AUTOMATIC FEEDING.

SPECIFICATION forming part of Letters Patent No. 742,198,6.ated October 27, 1903.

Application inta May 19, 1903.

To ctZZ whom it may oon/cern.-

Be it known that LWILHELM JOSTEN, a citi- Zen of the German Empire, residing at Neuss- Von-the-Rhine, Germany, have invented anew and useful Construction of a Device for the which the following is a specification.

My invention refers to devices for effectuating an automatic feeding of furnaces with the necessary fuel by the construction herein described,and illustrated by the figures on the drawings submitted herewith. The principal part is the grate, on hinges or otherwise movable, the fuel-supply being stored in a box attached on the outside of the stove or furnace to allow a convenient charging. said box is provided with a receptacle divided into several small compartments through which tne fuel is to pass.x The compartments are keptin their proper positions by means of a catch until the fuel on the grate supplied through one of the former is so far consumed that the grate being relieved of the weight of so much of the fuel as has been combusted and being actuated by a weight or spring, as hereinafter described, will be lifted and the aforementioned catch disengaged for an instant, ashort movement of the receptacle being caused thereby just far enough to bring the compartment next in turn to a mouth through which the fuel is dropped upon the grate.

In the accompanying drawings, Figure l is a longitudinal section of a stove provided with my improved fuel-feeding apparatus, showin g the grate lowered. Fig. 2 is a similar section with the grate raised. Figs. 3 to 6 are details of the detent mechanism; Fig. 7, a longitudinalsection of a modification of the apparatus, and Fig. 8 a longitudinal section through a further modification.

In the stove A (represented by Fig. l) the grate r suspends at its extended end from a hinge c or other suitable hold attached in the rear side of the box a, containing the slidable receptacle or magazine b, provided with a series of superposed inclined pockets or compartments. A weight g is provided catching below the extension of the grate or the grate itself by a suitable lever d and compelling the latter to make an upward movement when the fuel holding it down has been The l serit1N0.157.855. uit man.)

sufficiently consumed. `At the same time a detent mechanism or catch disengages for a moment and allows the moving downward of the receptacle b, as aforementioned. (See also Fig. 2.)

The details of the catch are illustrated more particularly in Figs. 3 to 6.

On the spindle s of a drum B, over which is directeda chain e, carrying the receptacle b, there is a ratchet-wheel f, into which engages a pawl h, actuated by aspring q. Below the said pawl there is a perpendicular bar t' on the box a, which at its upper end has a movable piece 7c, also actuated by a spring 7c', the effect being that when the bar i is raised from the grate r the said piece k catches below the said pawl h,throws the latter out of engagement with the ratchet-wheel f, and is instantaneously pressed aside by a projection Z, Figs. 5 and 6. After the receptacle b has thus been allowed to descend for the height of one compartment the pawl h reengages the ratchet-wheel f, so that the receptacle is relocked in position. In this way a layer of fuel is delivered to the mouth n of thefire-door m and will glide down upon the grate r along the inclined bottom of the compartment. A y

In Fig. 7 the grate ris retained in the front of the stove and the lift is eectuated by a.

spring o 'insteadof by a weight when the fuel has been consumed. so set that'it can be adjusted to makev the pressure exerted by it more or less strong at wish, and thus the thorough combustion of the fuel may be regulated before the feeding of a new charge is edected.

In Fig. 8 a grate isprovided which consists of two halves. In this case both of the latterf are permitted to make a downward movement, whereupon the receptacle-b will disengage. This figure shows the parts of the grate in lowered position, which is the position after the feeding of fuel.

The grate might as well-be retainedinthe side wall laterally from the fuel-magazine, or it may suspend like the beam of a balance, or it may be so arranged that its entire surface will descend.

What I claim as myinvention, and desire to protect'by Letters Patent, is-

1. A fuel-feeding appfiratus composed of a The said spring may be IOO movable grate, a slidable magazine havinga for looking the drum, and a rod operated by 1o number of compartments, a magazine-loekthe grate and adapted to release the paWl, ing device, and means controlled by the grate substantially as speeifed.

for releasing said locking device, substan- Signed by me at Dusseldorf, Germany, tially as specified. this 42th day of May, 1903.
